I agree with Stephen that the world of the media, and journalists 
themselves, are just a wee bit more complex than Chris would have it. 
And I think it is important to distinguish between reports on matters 
in which science figures by non-science journalists, and those written 
by science correspondents. (A casual check on Ben Goldacre's "Bad 
Science" blog reveals that many of the articles that he rightly 
castigates are not written by science correspondents.) Writing from 
this side of the pond, I can assure you that there *are* intellectually 
honest science journalists, for example Mark Henderson of the London 
Times and Robert Matthews, former science correspondent of the Sunday 
Telegraph and now freelance. To suggest that such journalists are 
little more than newspaper hacks is simply untrue.

I see that even poor old Ben Goldacre of "Bad Science" fame can't 
escape Chris's castigation:
>But what he has done is figure out a way to make good science
>journalism "sexy": he badmouths other journalists (and scientists)
>who do exactly what they are paid to do (viz., make science
>salable to newspaper readers). It's good old "gotcha" journalism.

As Chris is evidently unable to credit anyone in the media business 
with any integrity he represents (or misrepresents) even the invaluable 
work that Goldacre does in terms of hack journalism – he's found a way 
of making even good journalism "sexy".

Not that I think that Ben Goldacre escapes criticism completely (who 
does?), though in this instance it is in relation to his blog rather 
than to his published Guardian column. I note that among the topics 
listed on his blog he has a section headed "Media" containing links to 
his blog articles. This includes several British national newspapers, 
but missing are The Guardian and the Guardian-owned Sunday paper The 
Observer. Now this can't be because no doubtful scientific stories have 
been run by these newspapers, because a quick search reveals that 
Goldacre himself had written on at least a couple of Observer articles 
on his blog (with at least one that he published in the Guardian, about 
a major autism/MMR scare story in the Observer) – not to mention an 
Observer article as recent as 20 September this year that warned that 
"health officials will not be able to stem the growth of the worldwide 
H1N1 pandemic in developing countries. If the virus takes hold in the 
poorest nations, millions could die and the economies of fragile 
countries could be destroyed."

Incidentally, this latter story is of interest in that (a) it was not 
written by a science correspondent, and (b) it could not really have 
been said to have been sensationalised by the journalist, as he was 
simply basing his story on a UN report (though one would hope that a 
responsible science journalist would have treated the report with a 
modicum of scepticism). This illustrates that there are numerous 
complexities in the reporting of science in the media, ranging from the 
extreme position taken by Chris, to the more nuanced position of 
Stephen's.

I said, deploring a news article on the dangers of pot for
teenage brains from a report which failed to mention that the
research was on rats:

Nothing. As I said, why they did is obvious. I was deploring it.

Some are both. Not all are shameless hacks intent on
sensationalism. Some write excellent and intellectually honest
accounts. As you note, there are good science journalists.

What I was bemoaning was not that a journalist tried to foist this
crap on us, but that it came straight from the press release of
the McGill University Public Relations and Communication
Office. Here's what I said:

"It's not  the fault of the science daily journalist, though, because
this egregious misinformation is present in the original press
release from McGill University. Shame, McGill!
http://muhc.ca/newsroom/news/cannabis-and-adolescence-
dangerous-cocktail or http://tinyurl.com/yhyedn5

Interestingly, I just checked the news report on this as it
appeared in our major local paper, the Montreal Gazette, and I
see that the reporter showed some initiative in restoring the
missing information about it being a rat study (at
http://tinyurl.com/yjzh4uh). The reporter also elicited this gem
from the senior investigator, "Although the research was carried
out on laboratory rats, Gobbi said, one can assume the same
effects on the human brain."  Did she say that with a straight
face?

I liked some of the comments, particularly this one from Logic
Barbeque: " "Just because marijuana is a plant doesn't mean it's
harmless.'"  What, really?  And here I thought poisonous
mushrooms couldn't hurt you."

"Gazette: your headline should read "Toking teen rats risk brain
damage".  Please correct it.  Thanks!"

And this one, from ER Doctor: "This "research" was done in rats
with WIN55,212-2, a very powerful synthetic full cannabinoid
agonist. It cannot be cavalierly extrapolated to say anything
concrete about adolescent human use of cannabis, a weak
partial cannabinoid agonist agent."

> There's nothing surprisingly
> egregious about this particular article, is there?

Yes. I've never seen a university press release, which should
have been vetted by the authors and presumably ran with their
approval, hide the fact that the research was in animals.

That's disturbing, and well worth fulminating over. Or maybe I'm
just excitable.

What is it that surprises you about this Stephen? The "news" is a
commercial product. Commercial products are routinely adjusted to 
ensure
that they sell to the greatest number of people at the highest price 
(or
rather, those that are not so adjusted, quickly cease to be commercial
products). Surely it became clear to you long ago that journalists are
not scientists (as if no scientist ever "turned a phrase" in order to
make his or her work seem more exciting to the public), and certainly 
no
journalist's boss is a scientist. Their values lie in a different place.

There are, to be sure, some good science journalists. Ben Goldacre of
the Guardian comes to mind. But what he has done is figure out a way to
make good science journalism "sexy": he badmouths other journalists 
(and
scientists) who do exactly what they are paid to do (viz., make science
salable to newspaper readers). It's good old "gotcha" journalism.

It is, of course, worth pointing out that the the pot-hurts-brains
article was BS, but being outraged seems a bit, well, disingenuous.
Almost all reporting on illegal drugs in the mainstream media is BS, 
and
has been since the 1960s -- from pot-is-addictive, to
LSD-causes-genetic-damage, to crack-babies, to the
suburban-crystal-meth-epidemic. It's all BS. There's nothing
surprisingly egregious about this particular article, is there?
